Abstract

The present disclosure provides a method for molding a pipe body that can inexpensively mold a pipe body having a tapered portion radially outwardly projecting relative to a large-diameter portion. The method for molding a pipe body comprises: molding of a tubular body by bending an unfolded stock so as to wrap a core metal; and removal of the core metal from inside the tubular body. The core metal comprises a first core metal piece for molding a projecting portion of the tapered portion. During the molding of the tubular body, the first core metal piece at least partly abuts on an inner surface of the projecting portion of the tapered portion, and does not abut on an area of the inner surface of the large-diameter portion located in an opposite side of a central axis of the large-diameter portion from the projecting portion.
